i i FARM-GATE.

SPECIF'ICATIoN` forming partV of Letters Patent N0.`2 24,915, dated February 24, 1880.

' Appncatnon med July 30,1819.

To all 'whom it may concern l Be it known that I, SAMUEL G. HURLBUT,

of Elyria, in the county of Lorainand State of Ohio, have invented certain new and useful Improvements in Farm-Gates; and I do hereby declare that the following' is a full and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference marked thereon, in which like letters refer to like parts in the different figures. Y'

To enable others skilled in the arts to make and use my invention, I will proceed to dei y scribe its construction and operation.

In the drawings, Figure l is a horizontal j secton,Fig. 2 isa plan view, Fig. 3 is a side y elevation, Fig. 4is a vertical section, and Fig.

i 5 is a side elevation, of gate.

`The nature of my invention consists in the construction and operation of thatclass of farm-gates which are opened by sliding backward in the direction of the fence a portion or the whole of their length upon a pivoted roller, and then swinging said gate around to a position at right angles to the line of its former position.

` My invention relates more particularly to the construction and operation of a hinged roller onwhich said gate slides.

In the drawings, A represents a bar, which `isconstructed in the form seen in Figs. l, 2,

73,and 4, having through its center a hole7 which serves as a bearing, and receives a jourl nal, c, of wheel B. Said bar A is, at its extremities, provided with journals d d', which are sunk below the surface of the bar, so as to form shoulders e e f f. In practice they are i cut in a concave form, so as to t a round rod,

such 'as eyebolts are usually made of.

g g represent twoeyebolts, which are sei cured to the post in the usual manner, and eX- tend around the journals d d and engage them in such a manner as to form bearings,in which they work freely, while at the Sametime each' eyebolt serves as a support for said bar, the

r shoulders e and f of said bar both resting upon their` respective eyebolts, thus bein g sustained inl a vertical position by their mutual strength.

B represents a wheel, which is constructed in the form seen in the drawings, Figs. l, 2, 3,

Iand 4E, in which c represents a journal, which is formed in the center of said wheel within an annular recess. Said journal is so positioned as to bring its bearing-point, when in operation, within the thickness of the wheel, in order to bring it as nearly as practicable under the center of grav-ity. Said recess is formed by ange i, which said flange forms the rim of said wheel. Said tlangez' is webbed to the journal c, as seen at j, Fig. l.' Upon the outer surface of said flange i, and at its eX- treme edges, are formed other flanges, K K', which are designed for the purpose of engaging and holding the bars of the gate, as seen in Fig. 5. y The gate is constructed in the form seen in Fig. 5, havingV its bars arranged and secured in position in the usual manner employed in the construction of such gates. At the center of said gate a vertical crossbar, Z, is secured to the horizon tal bars, and is at that point, between the bars that en gage the wheel, recessed out, as seen at m, so as to admit the free passage of the wheel, in order that the gate may be forced back to any desired distance beyond its center.

The operation of my gate is as follows: The

the eyebolts, by which it is held and supported lin a vertical position in such a manner that the weight is supported by the combined strength of both eyebolts. The journal c is inserted and secured in the bearing, so thatit can revolve freely. The vertical center of bar A coincides nearly in the center of gravity by reason of its being within the thickness ofthe wheel. The gate is then placed in position, as seen in Fig. 5, and may be forced either backward or forwardas desired, or turned from a right line to an angle of forty-five degrees, or, if desired, to an angle of ninety degrees, more or less, at the will of the operator.

The gate may, when partially or fully opened, have its ends supported on a hook or otherwise, as seen at n, Fig. 5.

I am aware that a patent has been granted to J. B. Bolinger for an improvement in farmgates, wherein he claims the wheel with a journal and its two integral arms in combination, when constructed, as described in his specification, with two eyeholts; but I am not aware that a gate wheel and hinge has 'been con- IOO strueted having a straight bar, A, a central bearing, c, placed as described. and having shouldered bearings at its ends, as seen at e e j' j", for the purpose of suspending the Weight 5 equally upon two eyebolts, as described.

I claim- The oscillating vertical bar A, provided with a central bearing, and With shoulders e e f f' near its extremities, forming recesses d d',

1o in combination With the eyebolts g g', and with the Wheel B, having projecting journal c, which latter enters thevcentra-l bearing, and thus allows the bar or bearing' to stand Within the enged rim or annular recess of the Wheel, substantially as herein shown and described. 15
